GAS-RETORT.

Specification of Letters Patent No. 32,802, dated July 9, 1861.

To all whom it may concern:

Be it known that I, A. K. TUPPER, of Porn tiac, in the county of Oaklandand State of Michigan, have invented a new and useful Improvement inGasRetorts; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1, is a longitudinal vertical section of a retort with myimprovement. Fig. 2, is a transverse vertical section of the same. Fig.3, is a horizontal section of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists in the construction of a retort for makingilluminating gas from rosin, oil or other substance which can beintroduced in a liquid state, with two upright chambers side by side,one of which having the feed pipe attached contains a series ofpartitions inclined longitudinally in opposite directions alternatelyand provided with openings to allow the liquid substance to run from oneto the other from the top to the bottom of the series, so that all maybe converted into gas or vapor before passing by an opening near thebottom to the other chamber to which is connected the outlet pipe and inwhich the decomposition of the vapors are completed.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A, B, represent the two chambers of the retort which with the exceptionof its having one or both ends made separate and movable, may becomposed of a single casting, the chambers being narrow, upright ornearly so and separated by an upright partition a, which is only thickenough to give the requisite strength, said partition having an opening0, near the bottom to constitute a means of communication between thetwo chambers. A, is the inlet chamber having the inlet pipe 6, for theintroduction of the melted rosin or oil to the retort, arranged at thetop of the said chamber and near one end thereof.

(Z, (Z (Z are the longitudinally inclined partitions in the inletchamber A, extending all across the said chamber and so nearly from endto end thereof as to leave only a small opening 6, at the lower end ofeach, the said opening in each of said partitions being at the oppositeend of the retort to that in the partition above or below it. Theinclination of the uppermost partition (Z, is downward from the inletpipe Z), and the inclinations of the others are reversed alter nately.The opening 0, is arranged under the highest portion of the lowestpartition (P. The partitions (Z, al (Z are represented in Fig. 2, asinclined transversely, but this is immaterial as their transversearrangement may be horizontal. The outlet chamber B, has no partitionsbeing simply a plain chamber. The outlet pipe f, is arranged at the topof the said chamber 13, and near the opposite end to that where theopening 0, is situated.

The retort may have the sides perfectly fiat as represented or of otherform, and is to be so exposed to a fire in any suitable manner as toheat both its sides and its bottom. The melted rosin or fluid matterintroduced at Z), dropson to the partition (Z, and flows down thatpartition to its opening 6, through which it drops to the next partition(Z and so on, flowing down the several partitions back and forth fromone end to the other of the retort and being thereby vaporized andpartly decomposed into gas. The gas and vapor pass together through theopening 0, and the decomposition is completed in the chamber B.

By the use of this retort I am enabled at the same time to manufacturefrom rosin very economically, illuminating gas and lamp black of thevery finest quality the latter being deposited all over the surfaces ofthe chambers of the retort and its removal being easily effected on theremoval of one of the movable ends of the retort, and it is in thismanufacture of lamp black simultaneously with the manufacture of gasthat I consider the advantage of my invention to consist.

I do not claim the invention of a cellular retort; nor do I now claim aseries of reversed inclined gutters Within a retort as chamber B,Without partitions on the oppothat is claimed in my Letters Patent ofMay site side of it, all substantially as herein 10 22, 1860. Butspecified.

What I claim as my invention and desire 5 to secure by Letters Patent,is, TUPPER' The combination in the retort, of the up- WVitnesses: rightpartition a, the reversed inclined par- M. E. CRoFooT,

titions (Z, (Z (Z on one side of a, and the JAs. S. DENNY.
